Understanding the LCD display

The front panel LCD provides important information to the operation of the LR-100:

Channel: This indicates the currently tuned channel. See “Which channel should I use?” below for more information and the Channel Selection Chart on page 22.

RF Power: This indicates the relative power from the transmitter. You should maximize the level for best operation.

Which channel(s) should I use?

Your LR-100 gives you the ability to select both wideband and narrowband receiving chan- nels, so finding a clear reception channel should not be difficult. Listen recommends the use of wideband channels (channels designated with a letter on 72 MHz or starting with a “2” on 216 MHz), unless you are interfacing with an existing narrowband transmission system. Before turning on the system transmitter, use the “Seek” button to find any other transmitters that might be in the area. Choose a channel with the least amount of interference for your opera- tion, and set your transmitter to this channel.

If you are using multiple channels at the facility, follow this process:

a.Same Space: If your transmitters are located in the same space (i.e. an equipment rack), you can only use six channels at 72MHz or three at 216MHz. With all of the transmitters off, listen for interference on the wide band channels (listed on page 22 in the channel selection guide) via the headphone jack. Do not attempt to use channels that have noticeable interference. Now choose the channels with the widest channel spacing. It is recommended that adjacent channels in a facility be spaced at least 300KHz. If there is no interference the following channels are recommended: A, C, E, I, J, and H for 72MHz and channels 2A, 2K and 2V at 216MHz.

b.Distributed Spacing. If you are using transmitters that are spread out over space, you can have more simultaneous broadcast channels. You can use adjacent channels (see
